RULlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 441,905, dated December 2, 1890.

Application led June 2, 1887. Serial No. 240,054- (NO model.)

To @ZZ whom it may concern,.-

Be it known that I, ALONZO SEDcwIeK, of the city of Poughkeepsie, in the county of Dutchess and State of New York, have invented new and useful Improvements in Ruling-Machines, of which the following is a specification.

This invention relates to that class of ruling-machines in which the lines are formed upon the paper by means of thin disks or rings, to the edges of which the ink is applied. The lines produced by such machines are frequently broken or imperfect, especially when it is attempted to produce ine lines.

The object of my invention is to overcome this diiiiculty; and it consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure l is a longitudinal sectional elevation of a ruling-machine provided with my improvements. Fig. 2 is a top plan View of the same. Fig. 3 is a side elevation thereof. Figs. et and 5 are fragmentary sectional elevations, the sections being taken in lines' and y y, Fig. 1. Fig. G is a fragmentary longitudinal section, and Fig. 7 a cross-section showing a modified. construction of one of the su pporting-rollers on an enlarged scale. Fig. S is an elevation showinga modified construction of the inking mechanism.

Like letters of reference refer to like parts in the several figures.

A A represent the side'frames of the machine, and Ct the horizontal main shaft journaled in the same.

B represents the feed-tapes by which the paper is supplied to the machine, and which run around a tape-roller l), journaled in the side frames A A.

b is a pressure-roller resting on the tapes above the tape-roller t.

C represents the lower ruling-cylinder, provided with a series of thin ruling-rings c, which are secured side by side to the surface of the cylinder in any suitable manner.

D represents the ink-fountain, from which ink is supplied to the rings c by an inkingroller E and an intermediate roller E. The ink-roller E is provided on its face with rings c, which correspond in arrangement with the ruling-rings c on the cylinder G, but are somewhat wider in their faces. These rings e elevate the ink from the fountain to the intermediate `roller E and the latter transfers the ink to the ruling-rings c. The spaces between the rings e permit the excess of the elevated ink to iiow back into the fountain on the descending side of the ink-roller and prevent the intermediate roller and the ruling-rings from becoming Hooded. A similar result is obtain ed b'y providing the intermediate roller E with inking-rings and constructing the ink-roller E with a plain face, as represented in Fig. S.

F represents the supporting or pressure roller, which is arranged above the rulingcylinder G, and on which the paper finds a support in passing over the ruling-rings. The roller F is provided with afiexilole or yielding surface, which adapts itself to the inequalities of the paper and enables a smooth and "l uniform impression to be produced. As shown in Fig. 1, the supporting-roller consists of a rigid core f of metal or other suitable material and a covering or outer jacket f of soft rubber. It may, however, be constructed in the form of a cylindrical brush f2, as represented in Figs. t3 and 7. In this case the bristles f3 may be clamped between collars f4, applied to the face of the roller.

G represents the upper ruling-cylinder, constructed like the lower cylinder G. Y II represents the lower supporting-roller, constructed like the upper supporting-roller F; I, the ink-fountain; J, the ink-roller, arranged in the same, and J the intermediate roller interposed between the roller J and the ruling-cylinder G.

ln the drawings each of the ruling-cyanders, supporting-rollers, inking and intermediate rollers is shown as composedof two sections arranged side by side upon the same shaft; but said cylinders or rollers may be provided with a single face or more numerous faces, as the desired style of ruling may require.

K represents the receiving-table, to which the sheets are delivered from the last rulingcylinder G.

ICO

Y frame A.

lis a gear-wheel secured to the shaft of the lower ruling-cylinder C and meshing with the wheel L. .l

Z is a gear-Wheel secured to the shaft of the upper supporting-roller F and meshing Vwith the wheel l; m, a gear-wheel secured to the shaft of the lower supporting-roller H and meshing with the wheel L, and m a gearwheel secured to the shaft of the upper rulingcylinder G and meshing with the Wheelm.

The wheels l and m are of equal size and larger in diameter than the wheels Z and m, so that the supporting-rollers revolveV with a `greater peripheral speed than the ruling-rings. As the supporting-rollers have a much larger surfacein contact with the paper than the ruling-rings, the speed with which the paper" moves past the ruling-rings is controlled by the peripheral speedof the supportingrollers, so that under the above-described proportions of the gear-Wheels, the paper moves past the ruling-rings with a speed greater than the peripheral speed of these rings. This differential speed produces a drawing action of the ruling-rings on the paper similar to the action of drawing a pen over paper and causes an equalization of the action of the lrings on the paper, whereby breaks or imperfections in the lines are pre- Vcnted. This permits very thin ruling-rings to be used and enables the machine to produce fine lines of even appearance. A similar effect is produced by causing the paper to move slower than the peripheral speed of the ruling-rings.

n represents a guide, which is arranged in advance of the ruling-cylinder C, and which directs the paper against the same out of a tangential line, so as to impinge against the ruling-rings thereof before the paper reaches the supporting-roller. This guide causes the paper to be wrapped around that part of the ruling-cylinder which lies between the' guide n and the supporting-roller F, as indicated by dotted lines in Fig. l. A longer contact of the paper with the ruling-rings is thus secured, whereby an additional safeguard is obtained against breaks or imperfections in the lines. A similar guide n is arranged in front of the second ruling-cylinder G. The guide n may be composed of a transverse rod and the guide nof a transverse plate, as shown in Fig. l. These guides avoid the necessity of lplacing'the supporting-rollers in close contact with the inking-rings, so that the fine relative adjustment of these parts which was heretofore required is dispensed with.r

By my improvements perfect lines can be that the sheets can be delivered directly from the ruling mechanism upon the receivingtable Without the interposition of carryingtapes or other mechanism for drying or delivering the same.

I claim as my inventionl. The combination, with a ruling-cylinder provided with ruling-rings, of a supportingroller and differential driving-gear connected with the ruling-cylinder and the supportingroller, whereby these parts are driven with differential peripheral speed, substantially as Set forth.

2. The combination, ith the ruling-cylinder and the supporting-cylinder, of a guide whereby the -paper is deflected out of its tangential course and caused to be wrapped around the ruling-cylinder, substantially as set forth.

3. The combination, with the ruling-cylinder, of a supporting-cylinder having its face composed of a cylindrical brush, substantially as set forth.

4. The combination, with theurnling-cylinder provided with ruling-rings, of an inkfountain, an inking-roller provided on its -"face with projecting rings, and an intermediate roller interposed between the inkingroller and the ruling-cylinder, substantially as set forth. y

Witness my hand this 26th day of May, 1887.
